34、be methods for direct assessment of odours in ambient air. This European Standard supplements the dynamic olfactometry method described in EN 13725 which is generally only suitable for measurement of odour emissions at source. As the practical lower detection limit is typically g951 10 ouE/m3, EN 13
35、725 cannot be applied to directly determine odour exposure in the field (i.e. measure faint odours at the concentration where they can just be recognized). The methods for measuring odour presented in this European Standard make direct use of odour perception, the effect of odorants on the human sen
36、se of smell. The standard involves the use of qualified human panel members in the field to directly assess the presence of recognizable odours in ambient air, and provide data that can be used to characterize odour exposure in a defined assessment area. The standard presents two key approaches as s
37、ummarized as follows: Part 1 describes a grid method which uses direct assessment of ambient air by panel members to characterize odour exposure in a defined assessment area. Part 2 (presented in this document) describes a plume method to characterize the presence of odour by determining the extent
38、of the downwind odour plume of a source. Although the ultimate application of this method is in monitoring the risk of exposure to odours and the resulting odour annoyance, there is no direct relation between the presence of recognizable odours and the occurrence of odour annoyance. The process lead
39、ing to odour annoyance being experienced by an individual or a community is highly complex. Additional investigations are necessary to establish a link between odour exposure and the risk of odour annoyance, which is profoundly influenced by odour exposure frequency, by the type and hedonic tone of
40、the odour perceived, and by the characteristics of those exposed to the odour (the receptor). The relationship between odour exposure and annoyance is not within the scope of this European Standard. The sensory methods described are only suitable for the assessment of odour in ambient air. They are
41、not suitable for the assessment of substances that cannot be detected by sensory methods, in particular when these substances may cause health effects not directly related to their perceived smell.

42、16EN 16841-2:2016 (E) 5 1 Scope This part of the European Standard describes the plume method for determining the extent of recognizable odours from a specific source using direct observation in the field by human panel members under specific meteorological conditions. The plume method involves the
43、determination of the presence or absence (YES/NO) of recognizable odours in and around the plume originating from a specific odorant emission source, for a specific emission situation and under specific meteorological conditions (specific wind direction, wind speed and boundary layer turbulence). Th
44、e unit of measurement is the presence or absence of recognizable odours at a particular location downwind of a source. The extent of the plume is assessed as the transition of absence to presence of recognizable odour. The primary application of this standard is to provide a common basis for the det
45、ermination of the odour plume extent in the member states of the European Union. The results are typically used to determine a plausible extent of potential exposure to recognizable odours, or to estimate the total emission rate based on the plume extent, using reverse dispersion modelling. The fiel
46、d of application of this European Standard includes the determination of the extent of the recognizable odour plume downwind from a source, under specific meteorological conditions (e.g. wind direction, wind speed, turbulence, etc. (see 7.3.2). This European Standard does not include: the measuremen
47、t of intensity of ambient odours; the measurement of hedonic tone of ambient odours; the measurement of the odour exposure in ambient air over a longer time period in an assessment area; the calculation of estimated source emission rate from plume assessment using reverse dispersion modelling. An ov
